Use of double bonds

Some synthetic uses of double-bonded functional groups... 

The intent of this review is not to cover all aspects of the use of double-bonded functional groups in synthesis but rather to cover recent developments that are hopefully of interest to the synthetic community at large. Other chapters in the present volume cover some other reactions of double-bonded functional groups. 

Some synthetic uses of double-bonded functional groups up to about 90%, thus making this process a valuable one (equation 89). 

One of the major uses of double-bonded functional groups in organic synthesis is the preparation of heterocyclic compounds. These compounds are either target molecules of a particular synthetic sequence, or are key intermediates in organic synthesis. This section covers the synthesis of heterocyclic compounds by carbon-heteroatom bond formation or by C—C bond formation. Epoxidation of alkenes is not covered here, but in Section II.A. Subdivision, for ease of reading, is by ring size, for the most part.
